Natural Medicine Testing
A Natural Medicine Testing Facility is defined by Colorado regulations as a public or private laboratory licensed, or approved by the Division, to perform testing and research on Regulated Natural Medicine and Regulated Natural Medicine Product. It is considered a Natural Medicine Business under Colorado rules.
Note: An Owner of a Natural Medicine Testing Facility may not hold any financial interest in a Healing Center, a Natural Medicine Cultivation Facility, or a Natural Medicine Products Manufacturer.
An application for a Testing Facility License must include the following information:
- Documentation demonstrating that the address for the proposed Licensed Premises is permitted under the Local Jurisdiction’s applicable zoning laws for the testing, storage, distribution, or transfer of Regulated Natural Medicine and Regulated Natural Medicine Product.
